sure, computer fans run on the 12v rail of a PC powersupply,

heres a molex pinout


now the 12v(or yellow) and the ground right next to it is what the fans spin off of, so you can go to radio shack and buy a cheap wall power supply, this here runs at 1500mA, or will power a 1.5amp fan, or 18watt fan

alternatively you can go the easy route and buy a PC powersupply, find the pinouts to jump so it powers up and you can run as many pc fans as you like(i THINK you need to jump the green to any of the black grounds on a ATX connector, dont quote me though)
